My personal feedback:
Why does it have to be inside Myday? If you have a bad label you have to back out through 3 different screens and enter 2 more screens to scan and fix the label.
If I had to guess I'd say that most of the unaccounted product is due to disposition license plate label barcode printing errors. Because they look fine, they're on the product in the right spot, but they just don't scan for whatever reason
